To (ZZZ whom it may concern:

, Be it known that I, FRANK E. BECKMAN, a citizenof the United States, residing at Havel-hill, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in SoleEdge- Molding Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' This invention relates to sole edge molding machines for offsetting the edge of soles preparatory to the lasting operation.

When molding the edge of channeled soles the break in the sole is made directly opposite the between substance. To accomplish this the feed roll rides on top of the between substance, and a feather roll, having a face arranged at an angle to the face of the feed roll, bends the feather away from the main body of the sole. The face of the feather roll is generally constructed to just cover the feather and an edge gage is placed at the outer periphery of the roll to hold the sole in the angle between the feed and feather In treating different types of soles a separate feather roll must be placed in the machine for operating on each sole having a different width of feather. This change of feather rolls consumes considerable time and necessitates the use of a large number of rolls with the machine.

The primary object of the present invention is to provide an edge moldingmachine in which a single feather roll may be employed for treating all of the different types of soles, and an edge gage by which the different types of soles may be correctly positioned with relation to the feed and feather rolls.

With this and other objects in view the invention consists in the improved edge molding machine hereinafter described and set forth in the claims.

The various features'of the invention are illustrated in the accompanying drawings in which Figure 1 is aview in side elevation of the upper portion of an edge molding machine embodying the preferred form of the invention; Fig. 2 is an enlarged view of the sole molding rolls illustrating the improved feather roll and edge gage; and Fig. 3 is a front view of the parts shown in Fig. 2,

The edge molding machine illustrated in the drawings is substantially the same as that shown and described in the patent to Reid, No. 1,059,394, patentedlApril 22nd, 1913. The machine illustrated is provided with a feedroll 10, a feather or edge bending roll 12, and. a molding roll 14. The rolls 10 and 12 are mounted on the main driving shaft 16, and the molding roll 14 is mounted on a shaft 18 which is journaled in a pivoted carrier 20, that is moved about apivot22 by a pressure spring 28'. The rolls are all positively driven by connections with the main driving shaft 16. The parts illustrated above, with the exception of the edge bending roll 12, are the same in their construction and mode of operation as those shown in the patent above referred to.

The feather or edge bending roll 12 in the machine illustrated in the drawings has a construction similar to the ordinary type of feather roll, except that the feather engaging face is Wider than the feather of any sole which is to be treated. An ofiset 24 is formed at the junction of the feather and feeding rolls to receive the shoulder of a channeled sole while it is being molded, and since the shoulder is substantially the same depth for all of the various types of soles the offset 2 1 does not need to be varied. It has been customary to employ a feather roll having a feather engaging face of substantially the'same width as the feather of the sole to be treated, and to hold the sole shoulder against the offset 24 with an edge gage which projects across the peripheral edge of the feather roll. This type of feather roll and edge gage is illustrated in the patent to Reid cited above. To properly position the sole with the improved feather molding roll, an edge gage 26 is mounted directly opposite the face of the feather roll 12, and is adjustable in a plane parallel to the face of the roll. By this construction the edge gage may be set to bring the shoulder of a sole against the offset 24, and provide for practically any width of feather while using the same feather roll for all different soles. The edge gage 26 has a tongue-and-groove connection with a carrier 28, and may be adjusted along the face of the feather roll by means of a slot 30 in the edge gage, and a set screw 32 mounted in the carrier. To

vary the position of the edge gage with ref- "bending roll and ilClJllStilblG in a ing been thus described, What is claimed as new 1s:

1. A machine for molding shoe soles havmg, in combination, a feed roll, a molding roll, an edge bending roll and a gage mounted opposite the sole engaging face of the plane substantially parallel With said face.

2. A machine for molding shoe soleshaving, in combination, a feed roll, and anedge engaging roll having angularly arranged sole engaging faces, a molding roll opposite the angle formed by said faces, an edge gage fOl. determining the position of the sole mounted opposite the edge engaging roll, and means for adjusting the gage toward and from the feed roll.

3. A machine for molding shoe soles having, in combination, a feed roll, an edge bending roll, for engaging the feather of a sole, having a face wider than the width of the Widest feather to be operated upon, and an edge gage mounted on a carrier and adjustable along the feather engaging face for positioning soles of different Widths of feather.

4. A machine for molding shoe soles having, in combination, a molding roll, an edge. bending roll, a feed roll, a gage carrier and an edge gage mounted on said carrier which is adjustable in a plane substantially parallel With the face of the bending roll.
